Thanks for answer and examples ;-)
I want wrap library UnAceV2.dll which is provided without sources. 
(http://www.winace.com/) I can't change foo_callback and foo_do_something 
parameters.
The callback function is
INT __stdcall StateProc(pACEStateCallbackProcStruc State)
the do_something function is
INT __stdcall ACEListProc(LPSTR ArchiveName, pACEListStruc List);

Inside StateProc I can call my_callback function, and ACEListProc will be 
called inside native function. Native function can store env and others 
parameters. But how within StateProc refer to this env and other parameters? 
This parameters must be stored globally in data segment?
